Sony Vaio All in One desktop computer Model PCG-272L - Screen

Resolved Question:

Sony Vaio All in One desktop computer Model PCG-272L - Screen is white - but judging by HDD activity, the rest of the machine is functioning normally. Is there a video board that I can replace?

Hi, my name is XXXXX XXXXX I'd be happy to help you with this.

 

Unfortunately I wish I had better news. Let me explain.

 

The "white screen" happens on these machines a lot. It appears to be a problem with the video or video card, but that's not neccesarily the case. The display shows the white screen on power up until the video is initialized. Normally bios should initialize it during boot. The fact that you see HDD activity IS most likely point to it being a video issue, but that activity if it only lasts for a short time could just be the drive spinning up and initializing itself. If you see it running for a much longer period of time, then most likely you're correct and the machine is booting which means it is the video.

 

With all that said, there is obviously a failure of some sort in the video or motherboard. You've already checked the ram, which could result in it not booting. You also mention checking for lose cables. Assuming you checked all the video terminations, then frankly there isn't a lot more you can do.

 

The only real option if you want to keep the existing machine is to replace the motherboard. Pretty much everything is built into it, so replacing that will replace both the video and motherboard. Your local computer store should be able to order a replacement, or I'm sure it would be easy to find online from several dealers.

 

I'm assuming it's not still under warranty? It may be worth calling Sony if you aren't sure.

 

If you don't care about keeping the same machine, in a lot of cases when there is a complete failure like this, it's often times more practical to purchase a new machine and use whatever parts can be salvaged out of the old. The all-in-one doesn't leave a lot of options for that, but the hard drive (and it's data) as well as the ram and maybe even processor may be able to be ported to a new machine. Sometimes you may find it's not even worth doing that, you might be better off just porting the drive and getting better/faster ram and processor.

 

If you have any other questions about purchasing a replacement just let me know.

 

Wish I had better news!

 

Best Regards,

Greg

Let me check a couple of sources and see what I can come up with!

Question... If you look around or on the bezel do you see a different model number anywhere?
Expert:  Greg G replied 5 years ago.
I BELIEVE we're looking for a number something like: VGC-LSXXX

Yep found it VGC-LS35E
Expert:  Greg G replied 5 years ago.

Great! Let me locate some sources and I'll get right back to you!

Expert:  Greg G replied 5 years ago.

I checked all of the suppliers I normally use for parts and could only find one who actually stocked it... Thats here: http://product.pelltechnology.com/Sony_Vaio_VGCLS35E_Motherboard_Replacement.asp

 

However, let me give you a warning... I have ordered from this company a couple of times and have never had any problems. However, there are others who I have heard had HORROR stories about them. Again, I haven't personally experienced any issues, but considering the number of stories I have heard there must be something to it.

 

What I would recommend is frankly the same thing I would do if I were in that situation. I would first contact your local computer stores. Tell them you need a replacement system board for a Sony VGC-LS35E and see what they can come up with. If you would like I can even give you a link to a computer store which is operated by someone I know personally... They may even be able to process the order over the phone and have it drop shipped to you. That site is at http://www.bwave.com

 

If worse comes to worse, and nothing else seems available, then I would order from Pell... That's exactly how the orders I have placed have been done, when I had no other alternative.

 

Hope that helps!

Greg
